@6by9 Is this a valid change - i.e. do we get this using default software? |

It needs a comment to say that >120fps is only achievable with |

I can put the caveats on a superscripted footnote i.e. "For frame rates over 120fps, it is necessary to turn off AEC using I'll knock up a PR for review. |

OK, have updated the original PR, any comments? |

| <sup>1</sup>For frame rates over 120fps, it is necessary to turn off AEC using `-ex off` and AWB using `-awb off`. This will help maintain higher frame rates but result in lower quality images. We do not guarantee framerates over 120fps. |
There was a problem hiding this comment.
I've just checked - AWB doesn't have an effect.
"For frame rates over 120fps, it is necessary to turn off automative exposure and gain control off using -ex off. Doing so should achieve the higher frame rates, but exposure time and gains will be set to fixed values as supplied by the user."

Ship it. |

Thank you! |
